Bug Editor keeps crashing constantly

I am using 2022.2.13f (but this is happening from 2022.2.10f1) and the editor crashes every couple of minutes making it impossible to work on my project.

In the editor logs there only:

Code (csharp):

I doubt that it would crash on an empty project, but I won't be able to upload my project along with the bug report. Is there any way to narrow down or identify the cause?

I am on windows 10 & 11, using RTX 3080ti or 1660 Super. I also have the latest GPU drivers installed.

I've tried with parallel import enabled and disabled in the project editor settings. There is no difference.

I really need some help as it is not possible to use an engine that crashes every 5 minutes.

 

I'm having the exact same issue here with different versions of Unity from 2202.2.10 all the way to 2022.2.13

• RTX 2070 Super
• Windows 11
• Latest driver

I will try 2022.2.14 as this version was released this night. Lets hope for the best

UPDATE: Nope, just crashed again with 2022.2.14

 

Have you wiped the library after the engine update? It seems that it mitigated the issue at least in my case. It is still bad, but not as bad as before.

 

I tried that before but after a day or two the crashes came back.

What might help, is to set the Rendering API from Auto to something that does not have D3D11 in the first place. I am currently using D3D12 + D3D11 as version 11 in second place. So the editor is using 12 and did not crash at all until now.

 

Keeps crashing and DX12 is not working

@nehvaleem are you using the 3rd party plugin "Bakery" btw?

 

Nope, not in this project.

 

Hm was thinking its related to this :/

I updated to .17 but don't think this is fixed yet

 

Same issue in our team, for 4+ desktops.

 

Same here, 2022.2.19. Ryzen 5 3600, GTX 3070.
For me it almost only happen when I work with UI in the editor.

Any updates?

 

QA does nothing with bug reports that don’t instantly repro, and the people here don't seem to have the crashes narrowed down to straightforward reproducible steps.

Asking them to submit bug reports without super clear repro is asking them to waste their time.

 

Unfortunately that is exactly what happend to my bug report. One day after my submission I just got an e-mail, asking me about my experience with this issue, because "investigating my bug report was just finished". Never heard about it again.

The only really reoccurring thing is the

Code (CSharp):

1. d3d11: EndWrite on null buffer
2. d3d11: EndWrite on null buffer
3. d3d11: EndWrite on null buffer
4. d3d11: EndWrite on null buffer
5. d3d11: EndWrite on null buffer
6. ....

flood right before the crash. The crash itself is not consistently reproducible. I think I can narrow it down on two things:

1. Coming back to the editor (regaining focus) after a longer time
2. Almost after every light-bake. Which also somehow is a regain-focus thing because baking light takes some time
   

But it also happens when you are just working inside Unity. As I said, not really reproducible

 

Of course that's what happened. The purpose of QA is for both users and developers to feel like there is a system through which progress can be made while nothing is actually done apart from busywork.

I think the community should start translating "Please submit a bug report" to the actual meaning the systems in place at Unity give to that phrase, which is "Please go F*** yourself"

 

It looks like I wrote this message, lol

I think that regaining focus is an important factor. In my case - working with uGui often leads to a crash. It is really tough to work that way.

 

I too have something similar ("Calling EndWrite before BeginWrite") happening almost every day on 2022.2.18.

There's no way to "start empty project and give steps to reproduce".

The real problem is that this type of error messages have no stack trace or no information about what's causing it. Apparently this error has been there since 2021.3.25 but piling new features above other features makes this really shaky. Something obviously causing it (who knows if it's the prefab system or some missing script whatever) but there is zero way to debug this by ourselves.

 

I have an update to this: Today with version 2022.2.20 I got a traceable exception right before the crash for the first time. Hope it helps to find a fix:

41. d3d11: EndWrite on null buffer
42. Crash!!!

 

I removed "Range(...)" from INSPECTOR and after that I have not seen EndWrite error anymore. (Not sure if coincidence but several days without "EndWrite" error.

https://docs.unity3d.com/ScriptReference/RangeAttribute.html

 

Still searching for similarities here and @sandbaydev gave me an idea: Are you guys using Odin by any chance? Maybe, if we all have this in common, this is a starting point.

 

I am using Odin 2.x

 

I don't know if it is a viable solution, but maybe it will work in the short term. I have noticed that if I switch the editor to the DX12 version the crashes are a lot less frequent.

 

I can confirm the latest 2021LTS crashes constantly even after wiping the Library folder. It seems to be related with showing an inspector, but we are not using Odin.

 

As mentioned in another crash thread, @sandbaydev had a possible fix for some errors/eventual crashes by removing [Range()] attributes. See if trying this helps you or not: https://forum.unity.com/threads/calling-endwrite-before-beginwrite.1427973/#post-9047230

Dude same problem, happens like 3 times a day for me. Not looking forward to uploading my 5gb project.

Since it seems DirectX related, I'm going to switch to Vulkan for a bit to see if it stops.

 

I'm encountering the same problem, even the newest 2022.3.0f1 did not fixed the issue. I'm still working with 2022.2.5f1, which is stable for me. It happens randomly but will crash eventually after some minutes, e.g. on opening a prefab, just focus the window, selecting something. And also the error

d3d11: EndWrite on null buffer

in the Editor.log. I'm not using any editor plugins like Odin, just raw Unity.

 

It's crazy that a major bug like this can make it in an LTS Release so late in the release cycle.
Also the fact that unity wants a bug report with repro-steps even though it's a bug that basically everyone is encountering on Windows.

 

yeah, but I am afraid it isn't easily reproducible. I wasn't able to reproduce it on an empty or sample project.

 

Yep same thing here. Ever since upgrading my project to 2022, it crashes all the time - probably about 10 times a day. It will even crash when I'm not doing anything.
I wonder if Unity even has a QA team anymore or if they are just releasing untested software.

 

looks like Vulkan doesn't seem to make a difference.

I have the same crash. For me it started with 2021.3.25f I believe (+- one minor) so I bumped up to 2022.3.0f but that made no difference. I'm using Odin.

Edit: also getting absolutely spammed with error "EditorCoroutine handle is null." since upgrading to 2022

Unity Issue Tracker - Editor crashes on BufferD3D11::EndWrite when Hierarchy filter gives zero results on a scene with a custom UI Prefab (unity3d.com)

Everyone login and go vote for this to be fixed...

 

Doing this fixed it for me. Haven't crash yet all day. Although I would still like to see a fix for this in DX11, as per my post above.

 

Yes, using DX12 is currently my only workaround to be able to finish light baking. Unfortunately switching to DX12 completely brakes my game-mode.

 

my unity editor keeps crashing every day...every hour! 2021.3.26f1 2022.3.0f1 2023.1.0b17
it has been like this for month, very crash report is the same.
